Smartphone apps can measure noise exposure in spin classes. However, average noise levels exceed recommended daily limits, posing a risk for noise-induced hearing loss.
Area of Science:
- Audiology
- Occupational Health
- Mobile Technology
Background:
- High noise levels in exercise environments like spin classes can pose a risk to hearing health.
- Understanding and quantifying noise exposure is crucial for developing effective hearing protection strategies.
Purpose of the Study:
- To assess the feasibility of using smartphone applications for measuring noise exposure.
- To quantify the noise levels experienced by participants in indoor cycling (spin) classes.
Main Methods:
- The SoundMeter Pro app on smartphones was calibrated and used to measure A-weighted sound levels and noise dosimetry in 17 spin classes.
- Measurements were conducted according to National Institute for Occupational Safety and Health (NIOSH) guidelines.
Main Results:
- Participants were exposed to an average of 31.6 minutes of noise above 100 dBA per 45-minute class.
- This exposure level is nearly nine times the recommended daily noise dose, exceeding NIOSH guidelines for 100 dBA exposure.
Conclusions:
- Indoor cycling classes can generate noise levels that exceed safe exposure limits, potentially leading to noise-induced hearing loss.
- Smartphone-based mobile dosimetry offers a feasible method for individuals to monitor their noise exposure and take protective measures.

The Cardiac Cycle
The Process
Electrical signals—sent from the sinoatrial (SA) node in the right atrial wall to the atrioventricular (AV) node between the right atrium and right ventricle—cause both atria to simultaneously contract. When the signal reaches the AV node, it pauses for approximately a tenth of a second, allowing the atria to contract and...
Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
Cardiac Cycle
During the cardiac cycle, blood flow through the heart is regulated entirely by changing pressure gradients. This sequence of events begins with the heart in a state of total relaxation, known as mid-to-late diastole, during which blood passively flows from...
